Surfaces

A Fire surface.

Surfaces are a type of area. It is a flat layer of some type of substance that covers the ground, and has a unique effect when a creature steps on it. Many abilities and magical effects can create a surface, and they can sometimes be removed or converted into different surfaces with other elements or substances. The effects of surfaces can be avoided with abilities such as Fly.

The player can Dip their weapon into Fire and Hellfire surfaces to receive Dipped in Fire, and Simple Toxin surfaces to receive Dipped in Poison.

Ice, Lava and Web surfaces also impose Difficult Terrain, which doubles the cost of moving while on the surface.
